You'll find similar differences between the "feet and fists" death rate. What are the "feet" control laws?

And, the UK's low firearms death rates predate the firearms laws, which largely occurred post-WWI to stop a communist takeover.

Note the US' firearms death rate isn't uniform. For example, most of the peninsula's is better than the UK's best, but East Palo Alto, which has exactly the same laws (and lower firearms ownership than Palo Alto), is horrendously worse.

Parts of the US are third-world, with all that that entails. Gun control won't change that.
